UNITED STATES PATENT OFFICE 2,586,195 SMOKING PIPE Arthur R. Wood, New York, N. Y. Application February 21, 1948, Serial No. 10,079 s claims. (o1. iai-202) This invention relates to smoking pipes and has for an object to provide a pipe having improved smoking characteristics.

Another object is to provide a pipe of novel and improved construction.

Another object is to provide a pipe which is capable of completely burning its entire charge of tobacco without developing excessive heat or caking.

Another object is to provide a pipe having a ilter chamber through which the dry smoke passes and which contains a selected ilavoring material.

Various other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

In accordance with the present invention, the pipe stem is provided with upper and lower parallel channels extending between the pipe bowl and the mouthpiece. rIhe upper channel contains smoke filtering material and the lower channel contains an absorbent material. The pipe bowl and mouthpiece both drain into the lower channel so that nicotine and tars from the bowl and saliva from the mouthpiece are drained into the two ends of the absorbent material and thus removed from the smoke path. The upper channel also drains directly into the absorbent material so that all condensate is immediately removed from the upper channel as soon as it forms therein.

The upper channel may contain a plurality of perforated chalk discs and a iiller of cotton or other filter material which may carry a avoring material such as honey.

Although the novel features which are characteristic of this invention are pointed out more in detail in the claims, the nature of the invention will be better understood by referring to the following description, taken in connection with the accompanying drawings in which a specic embodiment thereof has been set forth for purposes of illustration.

In the drawings:

Fig. 1 is a top plan view of a pipe embodying the invention;

Fig. 2 is a vertical longitudinal section taken on the line 2-2 of Fig. 1;

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2;

Figs. 4, 5 and 6 are transverse sections taken;

on the lines 4-4, 5-5 and 6 6, respectively, of Fig. 2;

Fig. 7 is a perspective view ofthe cartridge case; and

Fig. 8 is a perspective view of a chalk disc.

Referring to the embodiment shown in Figs. 1` 8, the pipe comprises a bowl I5 of the usual shape and material, having a base I6 terminating in a ilange Il forming a trap chamber I8. A plurality of passages I9 extend between the bowl I5 and the chamber I8. These passages are distributed across the base I6 to provide a more nearly uniform draft than would be the case with a single passage and to thereby cause the tobacco to burn evenly across the bowl.

A connector 22, made of cork, rubber or other soft material, is formed with a transverse wall and an annular ange 23 seated within the chamber I8. A plug 24 of a solid adsorbent material such as chalk is disposed in the end of the flange 23 and is provided with a plurality of passages 25. A chamber 26 is formed in the connector 22 beyond the plug 24 which may be iilled with a suitable absorbent or ltering material such as a combination of mineral Wool and cotton.

A cartridge 30 comprising a peripheral wall 3| and a dividing Wall 32 extends from the connector 22 which is recessed to receive one end of the wall 32. The walls 3l and 32 may be made of a suitable material such as heavy paper. The wall 32 divides the cartridge 30 into an upper chamber 33 and a lower chamber 34. Passages 35 and 36 in the connector 22 extend from the top and bottom, respectively, of the chamber 26 to the chambers 33 and 34, respectively. The wall 32 is formed with a plurality of perforations 3'I which drain the condensate from the chamber 33 into the lower chamber 34.

The upper chamber 33 contains a section of lterv material 38 such as cotton which may be impregnated with a flavoring material such as honey. Alternatively dried fruits or vegetables or other flavoring material may be used.

At each end, the chamber 33 carries discs 33 of a solid adsorbent material such as chalk (Fig. 8) having transverse passages 43 therein and recesses 4I in at least one face to provide smoke chambers between successive discs 39.

The lower chamber is lled with a suitable ab sorbent material 43 such as cotton which may have'a. wick at each end extending through the passages 36 and 46.

The other end of the peripheral wall 3| of the cartridge 30 is secured over the reduced end of a mouthpiece 4l containing a connector 44 which may be made of cork or rubber. The connector 44 is recessed to receive the end of the wall 32 and has passages 45 and 46 extending from the chambers 33 and 34, respectively.

The mouthpiece or bit 4l has the usual axial passage 48. A small saliva trap 49 is formed in the mouthpiece 41 between the passage 48 and the end of the connector 44. The saliva trap 49 is shown as an oval shaped chamber` extending both above and below the passage 48 to pick up any condensation as well as moisture and drain the same to the passage 46.

The mouthpiece 41 and bowl I5 are addition ally secured together by a metal sleeve 50. The pipe may be disassembled vby removing the cowl l5 and mouthpiece 41 from the sleeve 50, pus-hing the cartridge 39, with connectors 22 and 44 attached, out of the sleeve, and then removing the connectors from the cartridge to expose the chambers 33 and 34.

It is contemplated that when the absorbent material 43 in the chamber 34 becomes satu-` rated, the entire cartridge 30 will be discarded and replaced by a new cartridge. However the absorbent material 43 may be renewed in the chamber 34 if desired.

In the operation of this pipe the nicotine and tars are trapped in the chambertZy and are absorbed by the material 43 in the chamber 34, following the wick through the passage 30. The smoke passes through the plug 24, chamber 23 and passage 35 into` theupper chamber 33 or" the cartridge 30 where it ispuriiied by` thechalk discs 39 and passesthrough the lter material 3B and the flavoring materialy therein.

Any condensate in the chamber 33 passes through the perforations 31 to the absorbent material in the chamber 34,. The dry smoke then iiows through the passage 45 to the mouthpiece 41. Any saliva from themouthpieceis separated in the chamber 49 and hows through the passage 46Vto the chamber 34 where itis absorbed by the absorbent material 43. The thin wick oi the absorbent material may` extendv from the chamber 34 throughV the passage 46 topickup streams, retards the heat transfer to the pipe, f

stern, and assists in ltering the tar to thereby assure a cool smoke.

Although a certain specic embodiment has been shown for purposes of illustration, it is to be understood that the invention is capable ot various uses and that changes and modifications may be made therein as will `be readilyvapparent, to a person skilled in the art.
